Answer: ![113.04ft^2](https://tex.z-dn.net/?f=113.04ft%5E2)
Step-by-step explanation:
![Formula: A=\pi r^2](https://tex.z-dn.net/?f=Formula%3A%20A%3D%5Cpi%20r%5E2)
![A=(3.14)(6)^2\\A=(3.14)(36)\\A=113.04ft^2](https://tex.z-dn.net/?f=A%3D%283.14%29%286%29%5E2%5C%5CA%3D%283.14%29%2836%29%5C%5CA%3D113.04ft%5E2)
Answer:
9 textbooks!
Step-by-step explanation:
Rucksack can hold = 6kg
Mass of textbook = 680g
So, here we need to show the division for finding the number of textbooks it can hold.
680 g in KG's = 0.68
Now, 6/0.68
That is 8.82 ( Round off = 9 textbooks)
Answer:
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
Step-by-step explanation:
Isolate then solve for x
![3x = 9+6\\3x = 15\\x = \frac{15}{3} \\x = 5](https://tex.z-dn.net/?f=3x%20%3D%209%2B6%5C%5C3x%20%3D%2015%5C%5Cx%20%3D%20%5Cfrac%7B15%7D%7B3%7D%20%5C%5Cx%20%3D%205)
Answer: 16
